WONDEE fuel tanker semi trailer (1)

A semi-trailer is a trailer whose axles are placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and is equipped with a coupling device (king pin) that can transmit horizontal and vertical forces to the tractor. Part of the total load of the trailer is borne by the tractor.

Features: without power in itself, it carries the goods with the tractor, and driven by the tractor.

A semi trailer is one of the main transportation equipment for cargo transportation in the world. Applications: carrying container or cargo and other special purposes.

Usually, semi-trailers can be classified into fence semi-trailers, flatbed semi-trailers, lowbed semi-trailers, warehouse grid semi-trailers, van semi-trailers, container semi-trailers, dump semi-trailers, oil tank semi-trailers, bulk cement semi-trailers and car transportation semi-trailers and so on.
